Book excerpt: The Carolina Bays have posed a mystery since their discovery in the 1930's. They look like they were made by impacts, but they were not created by impacts of extraterrestrial bodies. Solving the puzzle of how the bays formed provides clues that can be used to confirm that the Earth was hit by a comet 12,900 years ago. The Glacier Ice Impact Hypothesis and the evidence provided by the Carolina Bays clarifies how the large animals that lived in North America and the Clovis people who hunted them died. The whole extinction event took place in less than ten minutes. The Younger Dryas cooling period that followed could have been triggered by the material ejected above the atmosphere by the comet impact.

Available in PDF, EPUB and Kindle. Book excerpt: Have you ever seen a comet? It is a marvelous experience, one that all humans can share, that spawns a deep yearning to understand the spectacle. Have you ever wondered what comets are and why astronomers spend so much time studying them? Now, a comet expert and an astronomical historian have come together to produce the unique book that you now hold in your hands. Using their several decades of teaching experience, the authors have concisely presented the information you need to comprehend these majestic apparitions that grace our night skies. No mathematical proficiency is needed, in fact, this book doesn't contain a single equation! Comets are cosmic Rosetta stones, bridging our current knowledge by digging back to the earliest days of our Solar Systems. How did life arise on Earth? Did comets play a significant role in bringing water and the necessary organic matter to our early Earth? How about the dinosaurs? Were they driven to extinction by a cometary impact 66 million years ago? Comets may be both the enablers and destroyers of life on Earth as we know it. These are some of the tantalizing questions discussed here. If you so desire, steps are given to join the ranks of amateur comet hunters. Astronomy is one of the last sciences where amateurs play a significant role. Your reward for discovery? A comet officially bearing your name in the history books! The next Great Comet is on its way, we just do not know when it will arrive. Armed with this book, you will be ready to enjoy this unforgettable event.

Available in PDF, EPUB and Kindle. Book excerpt: ‘Incoming Asteroid!’ is based on a project within ASTRA (the Association in Scotland to Research into Astronautics) to provide scientific answers to the question – what would we do if we knew there was going to be an asteroid impact in ten years’ time or less? Clearly there are many things humanity can do nothing about, for example an unseen object traveling towards us so fast that we have no time to prepare, or an object so large it may be unstoppable. A realistic hazard model was decided upon, and the scenario developed from that: an incoming object about 1 kilometer in diameter, in an orbit ranging from the outer rim of the Asteroid Belt to within that of Earth’s. Three basic possibilities are considered in this book. The first is the deflection of the asteroid, using remote probes along with a number of possible technologies to change the asteroid’s course. Second is the attempt of a manned mission, in order to plant a propulsion system on the asteroid to push it into a different orbit. Third is the nuclear option, a last-ditch attempt to break up and then disperse the asteroid using nuclear weapons. (A rather impractical combination of these second and third options were used as the plot of the popular 1998 Bruce Willis feature film, Armageddon.) Although the cost of developing the technology needed to protect the Earth would be substantial, there would certainly be spin-off benefits. These could eventually result in practical small-scale atomic energy sources, new propulsion systems that could make extraterrestrial mining within the solar system a possibility, and other as-yet unforeseen benefits. And finally, Incoming Asteroid! considers the political implications - how governments across the world should best react to the threat with a view to minimizing loss of life, and in the weeks running up to the possible impact, preventing panic in the population.

Available in PDF, EPUB and Kindle. Book excerpt: Federal patronage of science was never contemplated by the framers of the Constitution, but they did seek to “promote the Progress of Science and useful Art” by granting inventors patent rights. However, direct subvention to scientists and scientific organizations was not considered appropriate activity of the central government. In the 19th Century, American science was funded almost entirely through private investors. Since WWII, however, the federal government has become the primary patron of American science. From the race-to-space in the 1950s to current furor over global warming, Bennett traces the subtle and not-so-subtle ways in which government has co-opted scientific research and reinforced a culture in which challengers to proscribed wisdom are frozen out. Citing original documents and media reports, Bennett offers a compelling, entertaining, and thought-provoking perspective on political influence on scientific research and its implications for a democratic society. "During the Nineteenth Century, almost entirely on private funding, American science grew from practically nothing to world class. Now, however, over fifty percent of American science is funded by the federal government. Dr. Bennett traces the path, "crisis" after "crisis," by which American science became practically an arm of the federal government. His tale is a cautionary one, warning against future "crisis mongers" who would extend the government's already majority control of American science even further. His warning is a timely one, and it should be heeded." Joseph P. Martino, author of Science Funding: Politics and Porkbarrel "Bennett's latest book offers a challenging interpretation of the rise of the American federal science establishment since World War II. Focusing primarily on the growth of the space program, Bennett argues that crisis, real or imagined, is the source of state power and state funding for science. The Doomsday Lobby offers what no doubt will be viewed as a controversial contribution to the history of American science policy, and more broadly to an understanding of the role of the state in society." James D. Savage, Professor of Politics, University of Virginia, and author of Funding Science in America

Available in PDF, EPUB and Kindle. Book excerpt: In 1993, the U.S. Department of Defense declassified information dealing with frequent explosions in the upper atmosphere caused by meteoric impact. It is estimated that impacts have occurred of a magnitude equivalent to the atomic bomb detonated at Hiroshima. Not all such space voyagers meet their end in the atmosphere, however; huge craters attest to the bombardment of earth over millions of years, and a major impact may have resulted in the extinction of dinosaurs. An impact in Siberia near the beginning of this century proves that such events are not confined to geologic time. Hazards Due to Comets and Asteroids marks a significant step in the attempt to come to grips with the threats posed by such phenomena. It brings together more than one hundred scientists from around the world, who draw on observational and theoretical research to focus on the technical problems related to all aspects of dealing with these hazards: searching for and identifying hazardous comets and asteroids; describing their statistics and characteristics; intercepting and altering the orbits of dangerous objects; and applying existent technologies—rocket boosters, rendezvous and soft-landing techniques, instrumentation—to such missions. The book considers defensive options for diverting or disrupting an approaching body, including solar sails, kinetic-energy impacts, nuclear explosives, robotic mass drivers, and various propulsion systems. A cataclysmic impact posing a threat to life on Earth is a possibility that tomorrow's technology is capable of averting. This book examines in depth the reality of the threat and proposes practical measures that can be initiated now should we ever need to deal with it.
